Audio Replay Enhancement with Key Segment Captioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in understanding fast-spoken text from interactive Question and Answer systems, voicemails, and videos, particularly when relying on assistive technology, as they need to manually replay sections multiple times, which is inefficient.
Innovation Solution
A method that determines when an audio input has been replayed a certain number of times, identifies key segments, translates them into the user's preferred language, and slows down playback while displaying closed captioning in the preferred language.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the Q&A system provides fast-spoken text responses, then the productivity of information delivery is improved, but the user's understanding and comprehension deteriorate
Solution Approach 1:
The patent segments the audio response into key segments that contain important information. When a user replays the audio, the system identifies and slows down only these key segments rather than the entire audio, allowing users to comprehend critical information without replaying the whole response multiple times.
Solution Approach 2:
The patent introduces closed captioning as an intermediary visual representation of the audio content. This intermediary provides text-based reinforcement of the spoken information, helping users understand the content without needing to replay the audio multiple times.
2Ease of operation
If the user manually replays audio sections multiple times, then the user understanding is improved, but the time consumption increases
Solution Approach 1:
The system performs preliminary identification of key segments before the user needs to replay. By pre-processing the audio to identify which segments contain critical information, the system prepares the groundwork for efficient replay, automatically slowing down only the necessary portions when replay is requested.
Solution Approach 2:
The patent changes the playback speed parameter dynamically based on user interaction. When a user replays audio, the system automatically slows down the playback speed for key segments, making them easier to understand without requiring multiple replays. This parameter adjustment directly reduces the time users need to spend replaying content.
3Adaptability or versatility
If the screen reader reads long paragraphs repeatedly, then the user accessibility is improved, but the efficiency deteriorates
Solution Approach 1:
The patent extracts key segments from the audio content that contain the most important information. For screen reader users, this means the system identifies and processes only the critical portions of long paragraphs, allowing users to access essential information more efficiently without needing to replay entire lengthy sections.
4Adaptability or versatility
If the Q&A system provides responses in a language different from the user's preferred language, then the adaptability is improved, but the user comprehension deteriorates
Solution Approach 1:
The patent introduces closed captioning in the user's preferred language as an intermediary. When the audio is in a different language, the visual text caption provides translation and reinforcement, allowing users to comprehend the content without needing to understand the spoken language fully.

AI summary
Provided are techniques for audio input replay enhancement. It is determined that an audio input has been replayed a pre-determined number of times. In response to the determination, a key segment in the audio input is identified and a preferred language of a user listening to the audio input is identified. In response to determining that a language of the audio input is not the preferred language of the user, the key segment is translated into the preferred language of the user. While replaying the audio input, playing of the key segment is automatically slowed down and closed captioning is displayed for the key segment in the preferred language of the user.
